. IMPROVEMENT IN Looms v The Schedule referred to in these Letters Patent and making part of tuve lame.'

To all whom it nui/y concern Be it known that I, WILLIAM Townsnnn, of Seneca Falls, in the county of Seneca, and ,State of New York, have invented a new and useful Improvement in Looms; andI do hereby declare that the following is a. full, cleaigandexact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the 'accompanying drawings, forming part of this speciication.

This invention relates to an improvement in looms, for weaving fancy cassimeres and other goods, having particular' reference to the method of operating theharnesses or heddles ofthe loom; and

The invention consists in operating the heddles by revolving a horizontal crank-shaft, in combination with sundry bars, rods, slides, and harness or heddle-gov'- ernors, as will be hereinafter more fully described;

Figure 1 is an'- elevationz of the loom, showing the Aheddles whichit contains, as squared, or as `standing in one position, showingr also the other parts of the loom in their proper positions.

Figure 2 is an. elevation, showing the same parts of the loom, 'but with the heddles changed, or occupying different positions.

Figure 3 is a top or plan yiew.

Figure 4 is a detailed view of the rail of the lower governor. Similar letters of reference indicate. corresponding parts. v

l The object of this invention is to so construct a loom as to dispensewith the great mass vof leversand pulleys which are now used for operating the harness or heddles-of looms in weaving fancy goods, such as fancy cassimeres, &c.

In carrying out my invention, I provide a properlyconstructed frame, which, in the drawing, is s een partly in section and is marked A.

'lransversely across the.iian1e,1 place thelay-shaft B, having 'a crank, O, in itsmiddle, by which motion is imparted to operate thelheddles.

In this example of my invention, Ishow but two heddles, but the operation for any number would be the same, while two will serve to illustrate the method and show .the mechanism by which they are operated.

D, fig. 3, is a horizontal bar, one' end of which is hinged to the frame, as seen at D.

This bar is' connected, near the other, end, to the.

crank Gby the rod E, so that as the shaft is revolved, the bar D is. given a vertical motion, correspondingcin extent with `the throw of the crank.

kF is the lower heddle-goveruor, the horizon-tal portion of which is shown in iig. 4.

G represents the upper governor.

The low'er one, F, is attached directly to the bar D by the connecting-rod F.

The upper one, G, is made to partake of' the motion of the bar D through two rock-bars, hh, which are hung by pins on stands t' t, supported bythe frame.

The inner ends of these rock-bars i 'i rest on the vibrating ba'r D, as vseen'atj, fig. 2, where they are confined by guardrods to force. them" down, so that they partake ofthe motion imparted by the crank, O.

The other ends of these rock-bars Aare 'connected with theupper governor G by rods k It. v

The action of the governors F and Gis s'uch that they approach each other, and recede at every revolution of the; crank.

l Thefends of each of these heddle-governors a're bent at right angles, so as to form guides, which slide up and down on the guide-rods l l, as seen at lm..

The two harnesses or heddles-of this loom are marked respectively,'fN and O, and they may be distinguished in the drawing by the shading or coloring, the, one marked O being orange, and the other pale blue, as seen in iig. 2.

VIn iig. 1 only one heddle is seen, as they are squared bythe governors, and in the view given, one is covered by the other.V

The tops of both are seen 1n g. 3.

Motion is imparted to the heddles by the governors, which have projecting arms.

The upper one, G, has two arms, pp, which project over the heddles, and by which any one or more oi' the heddles are supported, when their positions are changed in the process of weaving. l

The lower governor has one arm in its middle, which raises theiheddles.' This arm is marked 11, and is seen in fig. 3.

The heddles are supported or kept in an upright position by a 'vertical rod passing through the projecting ends of the top and bottom rails of cachas seen in the drawing at R.

These rods R are confined b v brackets S, projecting from the plate marked '.l.

Each heddle is provided with a sliding plate, u.

These plates stand on edge on top of each heddlc, and the change in the position of the heddle, (when a change is desired,) is etected'by the motion imparted to this p'late by any suitable mechanical device.

The'motionwhich is common to all looms for weaving fancy goods, and which is imparted by the Crompton chain, is suitable for this purpose.

To the outer endI of the plate u is attached a hanging rod, fu, which passes through abracket on the heddie, as seen at luf, and also through the eye of a hori zontal rod, a'.

The inner end of this rod x is supported by a hanger y.

Between the ends of the heddle and the vertical rod r, there is a spring, z, one end of which is attached to the end of the heddle.

'lhe other end passes through the eye of the rod fr, in contact with the rod e.

rlhe effect of this arrangement is to throw ont (or back) the slide u, by the recoil ofthe spring, for liberating the heddles from the upper governor-arms.

The way the heddle is held Aand controlled by the upper governor, is as follows:

To the inner end of the plate 1lthere a rod, ai', attached, with a hooked end, c.

lhe rod rests on the top of the heddle, as seen in the drawing.

d' represents guide-loops, which are attached'to the i top of the heddlc, which guide the slide fu, and also xthe hook c.

The rod a', it will be seen, is attached to the lower edge o f the slide Iu'.

011 the upper edge there is also a piece or pin, marked c'.

\Vl1en the crank on the lay-shaft stv-ands upright, the heddle may be changed by crowding in the slide u, when the pin c and the hook c' will catch over or on to the top of the arms p p, as seen in fig. 2.

In this position, the heddle may be held as long as desired, and be carried up or down, while the outer end of the slide will bear against the plate f', which may be made of glass, or of any suitable material, to lessen the friction.

The friction-plate f is supported by a stand, g', which is attached to the frame;

h.' is a spring, which is attached to the frame.

The upper end of this spring is bent at iight angles with the slide u, as seen more clearly in iig. `3, so that the horizontal portion bears against the outer end of the slide u when-the heddle is up, or the heddles are squared by the governors.

The Crompton chain, or other mechanical device for actuating the slide, is brought in contact with this spring, and the required motion is imparted to the* slide through the spring.

When not acted upon by the chain. or other mechanism, the spring recoils, or flies back, and leaves the slide free.

It will be understood, that in speaking of one heddle and the parts connected therewith, I speak of all, as they (be the number more or less) are operated in the same manner. I

I do not confine myself to the particular construction or arrangement of parts shown in the drawing.

The details may be varied without 'affecting the main features of my invention.

When the slide u is not acted upon by the patterncylinder, the heddle is drawn down by means of the arm on the lower governor, the spring forcing the rod a: under the same.

I claim as new, and desire to secure by Lettels Patent- 1. The governors F and G, constructed as described, and acting in combination directly with the hamess frames, substantially as herein set forth for the purpose specified.

2. 'lhe sliding plate a, and the parts connected therewith, and marked a c c fr fr, in combination .with the harness or heddle-frames of' a loom, arranged substantially as described, for the purposes specified.

3. The friction-plate f' and spring h', ill combination with the heddleframes,arranged substantially as and for the purposes described.

4. lhe combination ofthe bar 1) and rock-bars hl h, with-the governors F G, an'anged as herein described, for the purpose specified.
